Detailed Description

eDMA TCD.

This structure is same as TCD register which is described in reference manual, and is used to configure the scatter/gather feature as a next hardware TCD.

Member Data Documentation

ATTR

__IO uint16_t _edma_tcd::ATTR

ATTR register, source/destination transfer size and modulo

BITER

__IO uint16_t _edma_tcd::BITER

BITER register, begin minor loop count.

CITER

__IO uint16_t _edma_tcd::CITER

CITER register, current minor loop numbers, for unfinished minor loop.

CSR

__IO uint16_t _edma_tcd::CSR

CSR register, for TCD control status

DADDR

__IO uint32_t _edma_tcd::DADDR

DADDR register, used for destination address

DLAST_SGA

__IO uint32_t _edma_tcd::DLAST_SGA

DLASTSGA register, next tcd address used in scatter-gather mode

DOFF

__IO uint16_t _edma_tcd::DOFF

DOFF register, used for destination offset

NBYTES

__IO uint32_t _edma_tcd::NBYTES

Nbytes register, minor loop length in bytes

SADDR

__IO uint32_t _edma_tcd::SADDR

SADDR register, used to save source address

SLAST

__IO uint32_t _edma_tcd::SLAST

SLAST register

SOFF

__IO uint16_t _edma_tcd::SOFF

SOFF register, save offset bytes every transfer
